Can't debug tomcat application with gradle tomcat plugin

According to home page of gradle tomcat plugin FAQ section:

How do I remote debug my Tomcat started up by the plugin?

I need to add the following environment property:

GRADLE_OPTS = -Xdebug Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=5005

During run of container I should see information that it listens on particular port: Listening for transport dt_socket at address: 5005, but in my case it's not working.

How I can configure it properly ? I'm running intellij idea 14.1 Ultimate.

In my case it worked as I started the Tomcat in the IDE itself and not the CLI. For that I created two run/debug configurations, one for Tomcat and one to Remote connect the debugger to the Tomcat process.

For the Remote configuration, use the port 5005 like mentioned in the plugin FAQ debug section.

For the Tomcat configuration, you have to set the JVM settings explicitly. Simply put -Xdebug -Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=5005 as a value into the JVM options textfield in the Gradle run/debug config.

After both configurations have been created and properly configured, first run the Tomcat process and then connect to it by debugging the Remote configuration.

You can find an entire spring-mvc example and an detailed solution here.
